  Purpose: Lumican gene (LUM) is a candidate gene of myopia in MYP3 locus, and lumican is one of the major extracellular matrix components of the sclera.A mutant lumican (Leu 199 Pro, L199P) transgenic mouse model was established to investigate the axial length changes and ultrastructural features of sclera.
